# Database Migration Complete

## Files Created

1. **Prisma Schema**: `prisma/schema.prisma`
   - Comprehensive schema with all 18+ models
   - Supports SQLite, PostgreSQL, and MySQL

2. **Prisma Client**: `src/lib/prisma.ts`
   - Singleton pattern for Prisma Client
   - Proper cleanup in development mode

3. **New Database Layer**: `src/lib/database-prisma.ts`
   - Complete Prisma implementation
   - Maintains exact same API as old database.ts
   - All methods converted from spark.kv to Prisma

4. **Migration Script**: `scripts/migrate-to-prisma.cjs`
   - Backs up old database.ts to database-kv-backup.ts
   - Copies database-prisma.ts to database.ts

5. **Documentation**:
   - `docs/PRISMA_MIGRATION.md` - Migration guide
   - `docs/database/PRISMA_SETUP.md` - Setup instructions

## Next Steps

### Option 1: Automatic Migration (Recommended)
```bash
node scripts/migrate-to-prisma.cjs
npm run db:generate
npm run db:push
```

### Option 2: Manual Migration
```bash
# 1. Backup current database.ts
cp src/lib/database.ts src/lib/database-kv-backup.ts

# 2. Replace with Prisma version
cp src/lib/database-prisma.ts src/lib/database.ts

# 3. Generate Prisma Client
npm run db:generate

# 4. Create database
npm run db:push
```

## What's Changed

- **Storage Backend**: `spark.kv` → Prisma ORM
- **Data Persistence**: Key-value store → Relational database (SQLite/PostgreSQL/MySQL)
- **Type Safety**: Runtime types → Compile-time types with Prisma
- **API**: **No changes** - Same Database class methods

## Features

✅ Full type safety with TypeScript
✅ Relational data with foreign keys
✅ Connection pooling and optimization
✅ Easy to scale (SQLite → PostgreSQL)
✅ Migration tracking
✅ Same API - no code changes needed

## Database Models

The schema includes:
- User, Credential
- Workflow, LuaScript, PageConfig, ModelSchema
- AppConfiguration, Comment
- ComponentNode, ComponentConfig
- CssCategory, DropdownConfig
- InstalledPackage, PackageData
- Tenant, PowerTransferRequest
- SystemConfig, SMTPConfig, PasswordResetToken

## Verification

After migration, verify the setup:
```bash
# Check Prisma Client is generated
ls node_modules/@prisma/client

# Check database file exists (SQLite)
ls dev.db

# Start dev server
npm run dev
```

## Rollback

If issues occur:
```bash
# Restore old database.ts
cp src/lib/database-kv-backup.ts src/lib/database.ts
```

The system will fall back to spark.kv storage.
